I In carrying out my invention and as shown in the drawings, the crank shaft I is held stationary and upon vit are rotatably mounted a plurality of working cylinders A, each of which are of like construction with the several piston and crank rod connections, relatively so arranged that the firing or explosive operations are succession, that is to say, if there are five cylindersthe explosion after occurring in the first or No. l cylinder, next occurs in No. El cylinder, while N o. 2 is exhausting; No. 4' is drawing in a new charge and N o. 5 is making its thrust under a prior explosion, the thrust hundred and eight point O topoint the drawings.

Referring now more particularly to Fig. 3 of the drawing, .which shows one of the To all 'whom it may concern:

' Be it known v that I, ALBERT SCHINKEZ, .residing at Charlot-te, in-the county of Eaton and State ofMlichigan, :have invented a new and Improved Rotary-Cylinder Explosiveof which the `following is a. specifi- My invention, which relates generally to that ltype ofqinter'nal .combustion engines in ,vhich the working vcylinders rotate about a primarily has engine of the the operating parts are so designed whereby the engine will 4develop a maximum eiiiciency by reason for its object toprovide an degrees or from the operating parts, capable of being economi' indicated in Fig. 4 of cally manufactured, readily assembledv and provision is made'for positiveand uniform explosive actions in the several independently act-ing. working cylinmeans therefor, in its complete form, i desig- .nates the crank of the shaft- I, B the piston rod thatI couples the crankz' with the piston My invention, in its genericnature, comrangementof parts so combined -to produce a four cycle type of engine, adapted especially air craft, and in its more subordinate features, my invent-ion consistsV inv certain' details of vconstruction and peculiar combination of parts, all of fully explained, specifically pointed out iny the appended claims and illustrated in the accompanying drawings, in 'whichz- Figure l, is a perspective view of a comit being understoodthe vwalls o-f the several cvlinders A radiate from and form of a hub-like casing A that includes an axial or forwardly projected member M that forms a socket for the outer end of the shaft I and to which the propeller X is fixedly connected when the engine is utilized for aeroplanes and thelike.

The hub or casing A that carries the cylinders A has an axial opening a' at the inner side to provide for the desired adjustment of a cam disk K, the is bestshown in Fig. 2. v

The cam'disk K is ixedly mounted on the shaft and its lfunction isl to. control t-he opening'and closing of the fuel feed and the exhaust or residuum gases to and from the cylinders as will presently be'fully described.

Coperatively'joined to and rotatable with the several cylinders A -are the combined intakes and exhausts in the nature of hollow arms G-G and that rides upon the annular flange It on an inside hub H that is lixedly mounted on the shaft I. A long bearing sleeve P loosely mounted on the is located within the hub enlargement orv end disk to the frame that carries as to turn therewith.

As hereinbefore stated,

.designed that the p which is bolted the cylinders A so mum` weight ofthe driving mechanism` under a maximum efficiency. or thrust power.-

effected in alternate working cylinders and the valve actuating a partconstruction of which these radiate from a ring Gr- ,or impelling motion being one los Hand the sald sleeve has an annular The cam 'diskR before referred has a .A

pair of annular grooves, an inner one K2 and an outer one K and with these grooves co-v operate stub pins p one of which is provided for each of the cylinders and each of which controls the shifting adjustment of the single valve D hereinafter again referred to. The stub engaginggrooves'K2 and K are concentrically arranged except at a predetermined point where the said grooves join and form cross-overs 7c and 70,2, the purpose of which will presently appear.

The several stud pins p engage the grooves in the cam plate and to each of the pins is-pivoted the lower end of av'valve shifting rod F, the outer end of' which is guided through apertures in theA outer or angle ends g of the hollow arms or ducts G, which ends, as is clearly shown in Fig. 3, extend overthe single ports a in each of the working cylinders, controlled by a single lvalve D that is moved outwardly to and held closed by the internal pressure within the cylinders and which is mechanically shifted by a rocker lever E, one of `which is mounted on each of the angle ends gof the arms G and one end of which engages the outl Wardly projected stein d of the valve D while the other end engages the outer end of the valve shifting rod F.

By referring now more particularly to Fig.4 it will be seen that flange 7L of the fixedly held hub H has an annular exhausting port that extends one hundred and eighty degrees, the entire upper half of the hub, which hub, it should be stated, in practice, is made of two half sections. The lower part of the `ring has an inlet port that extends one half the distance between the .diametrically opposite ends of theV exhaust lopening, that is, between the beginning andv crates will best be understood by referring .particularly to Figs. 2, 4 and 5. Consideringvthe piston of cylinder number l as having a edm ressed working charge ahead of it, said cy inderis just in the position it sumes at the time of ignition. At this time the valve D is held closed by the 'force of expansion of the tired mixture. As soon as the .cylinder number 1 has passed the firl ing point it moves from the position shown in Fig. 5 in-a counter-clock-wise direction under the force of the exploded mixture, until it reaches a position diametrcall y oplposit@ to the position in which it is shown in Fig. 5, atwhich time the cylinder number l will have arrived opposite the point N in Fig. 4 so that the exhaust port will be in communication with the duct Gr so that as the cylinder l moves from position N to position O it will exhaust. Whilethe cylinder number l is'moving from the position shown in Figs. 5 and 4 around to a diametrically opposite position, the pin p rides in the groove K2 so as not to affect the valve D, As'

soon however, as the cylinder passes the pointN in Fig. 4, the .pin p crosses inte,

the outer groove K and opens the valve D,

thereby permitting the spent gases to exhaust, as the cylinder moves from position i N around to position O in Fig. 4. The cyl-- inder number 1 having made a complete revolut-ion from the vposition in which it is shown in Fig. 5,moves again from the position shown in fFig. 5 to a` point diametrically opposite 'to such position, while the pin p travels in the outer groove K and holds the valve D open so that as thel cylinder passes the port J it will receive fresh working agent. The cylinder number l having reached a position diametrically oppo. site that in which it 1s shown in Fig. 5, the

pin p is nowswitched back into the groove y K2 to permit the valve D to be heid closed as the piston compresses the charge during the movementof the cylinder from vthe opposite direction to that in which it is shownv in- Fig. 5 back t'o the'starting position in which the cylinder isshown in Fig. 5.' The operation of the other cylinders is precisely like that explained for the first vcylinder tired.

While I have shown and described the enginev as equipped with tive working cylinders and cranks, it4v is obvious a lesser or a greater number of cylinders may be employed, and further, vwhile I prefer to havethe crank shaft stationary and theV cylinders vrotate about the shaft, the generic feature vof my invention would appear were theshaft held to rotate and the cylinders fixedly secured. n

I am aware that rotatable cylinder engines with mechanism for successivelyv controlling the valves for the several cylinders` have been heretofore provided. My inven iio iis

tion, so far as I know, differentiates from what has heretofore been provided in this art in the manner in' which the cylinders, each with but a single combined inlet and exhaust port, are combined with the shaft and. a relatively stationarily held means for mechanicaliy sett-ing and positively holdingthe valve to its open positions while exhausting and while drawing in a new charge. Again, by providing a series of hollow arms that radiate f rom and have an axial bearing on a long hub at the inside of the crank end -of the shaft, a long rotary bearing for the member to which the valve shifting rodsare connected is also provided for, in such manner that great stability of the valve actuating means is effected, and Withthe usev of a minimum amount of ports' and Without the need-of springs or spring actuated shifting means'such as are. generally y necessary in the forms of engines of this' type heretofore provided.

The parts are of a lsimple arrangement."

and their construction is such that they .can be easily assemble'difr use and economically made.
